Maren, a citizen or the United States, and residing at Louis, 1n the State ot Mis souri, have invented certain new and useful Improvements in Stencil-Cutting Yitl'achines, or" which the following is a specii'ication.

This invention relates to stencil cutting machines and vone of its objects is to construct a machine in which the hlanli will he exposed to View at the cutting point, whereby the work of the machine is visible. Another object is to construct a stencil cutting machine in which the punches and lies lare adapted to operate on a clank positioned at an angle to the horizontal, and to provide means for supporting and feeding the blank in such a position with respect to the punches anti dies. l :Another object is to construct a stencil cutting machine in which the blank will not only loe visible at the cutting point but in which each stencil line after being cut is fully exposed to View so as to he in plain View heliore the operator.

Another object is to provide improved blank supporting and ifeeding ineens which is constructed and arrangedv to accuratelyv and positively feed the hlanlr.

Further objects will appear *freni the cletail description taken in connection with the accompanying drawings. in which:

Referring to the accompanying drawings, 10 designates a hase adapted to support the punch and die carrier. This punch and die carrier is or cylinclical construction ane either he formeel integral, or may be formed of two pieces secured together so to torni in eect a single element. is hownin the drawings the die carrier 11 the punch carrier 12 are secured t0- ether by screws 13. The punch and die arriersare separatefl "oy anannular space l adapted to receive the -hlank carriage ereinafter to he flescriheil, and are supi orteil on the hase i331 ineens of 1calls ring 19 clamped to the hase and taking over an inwardly projecting flange 20 serves 'to retain the punch and die carrier in posi` tion.. The punch and .die carrier is pro vided with a hand wheel or rim/21, pret-1 erably vcast integral with the carrier.

rlhe upper end of 'the carrier l1 has a Inachined face to receive aseriesof die plates 25 secured to the carrier hymeans oi' screws 26 in a manner well known to those skilled n the art. These die plates areforinecl with 'the usual stencil-charavcters anti the die carrier is recessed as shown at 27 to permit the punchings to drop out. A series of plungers icc ies

' against the yokes 33 secured to the plungersy 28 are mounted in bearings in the spaced annular lugs 29 and 30 on the punch carrier. These plungers support the punches 3l which are preferably separate plates secured to the plungers. The plungers 28are movedinwardly toward the center of the machine by means of springsv32 bearing by screws 34 and embracing pins35 mounted inthe lugs 29 and 30. The punches 31 and dies 25 may beof any suitable construction but are preferably constructed and formed in a manner hereinafter to be described.

- A bracket integral with the base 10 is Vproyided its upper end with a radially extending. bearing for an operating plunger or ram 4l having a hooked end adapted to engage a roll 50 in the slotted end of the pin or left side of the machine.

43, and a further connection between the lever 45 and the pin 43 is made by a small cross pin engaging a cani slot 51 in the lever. The lever 45 has a forked end coperating with aroll on the end of a lever 52 rigidly :connected to an operating rock shaft 53 vmounted on the base 10. This shaft extends across the machine and has its ends formed to receive anoperating handle 54, whereby the handle may be placed on either the right The shaft 53 is normally held-in a position with the arm in engagement with a stop 55 by a spring 56 connected at one end to the lever and at its other end to a pin 57 on the base l0. The lug 29 has mounted thereon a dial plate which is provided with the usual characters corresponding to the characters on the stencil punches and dies mounted on the punch and'die carrier. A stationary pointer 5) on.

lthe bracket 40 cooperates with the dial plate and positions the punches and dies at the cuttingA point as hereinafter described. skeleton stripper (3() is mounted on the bracket 40 integral with pointer 5i).

The base plate 10 has rotatively mounted therein a shaft (35 which is adapted to rcceive and support the blank carriage. This blank carriage is shown in detail in Figs. 4 l

and 9 and comprises a hub (ill having formed thereon thin radially extending arms 67 and provided with a rim 68 to. form a spider. The blank holding means connu-isos a. pair of upper Haring rims 6'.) and 7U and a lower flaring rim 71. connected by'vertical narrow strips 72. These strips 72 are preferably integral withthe upperrims and are secured to the lower rim in any desired manner, as by electro-welding- The rims 69, 'TO and 7l and the connecting strips will thus form a cyindrical element of skeleton construction, and this element is secured to the rim G8 in any desired manner as by screws or by electro-welding, the skeleton element being preferably so positioned on the spider that. the strips 7iwill come opposite the arms 67. The hub (it) is splined on the shaft by a, key 73 in the shaft engaging a keyway in the hub, whereby the carriage will move with the shaft but is prevented from rotating with respect thereto. The stencil blank can be inserted between the rims GS). and 7l and the strips T2 and will thus he positioned in cylindrical form in the recess 14. The frictional clamping action of the skeleton element will ordinarily be sufficient to hold the blank in position in the carriage, but the rims (5%) and 7 0 may be provided with alined holes 74 adapted to receive a pin, which pin may bc passed through the blank to hold it against movement in the carriage.

The fiared construction of the rims permits easy insertion of the blank.

The means for rotating the blank carriage step by step will now be described. lleferring to Figs. 3, 5 and (i, 75 designates a collar on the shaft (S5 forming a thrust bearing for the shaft. and this shaft is further secured against endwise mowmcnt by means ofa washer 76 and lock nuts 77. The lower end of the shaft has mounted thereon a ratchet- 78 which is clamped in position by means of a nut 71). A pa wl 8() sliding in a horizontal guideway- Si formed in a lug on the base. 10 hasa connection with an arm 83 on the rock shaft 53. The pawl is jointed as shown at 34, and a sin-ing H5 normally tends to move the pawl toward the ratcl'ict. Ihe pa wl is provided with cam faces Sb and 37 adapted to be engaged by pins Se and 8U respectively, extending downwardly from the base. rl`he parts are so constructed that when the rock shaft 53 is in its normal position thc pawl will be held out of engagement. with the ratchet by the pin SS, and when the rock shaft is in its other extreme position the pawl will again bc held ont of engagement with the ratchet by the pin 3S). l)ur ing the lirst part of the movement of the rock shaft 5I; the pawl will move into engagement with thi` ratchet and rotate the carrier one step` and this pawl will be moved out of en .',agmnent duringr the last part of the movement of the rock shaft.

'The means for moving the carriage vertically step b v step will now be described. .liefen-ring to Figs. I'S. T and n, ll() designates a lugpreferably madf.l integral with the base and bored to provide a bearingl for a, slidingr shaft ll. This shaft has a. laterally extending arm l2 which has pivoted thereon a incensi.

In ac- 'ih die invention' the punch and n 2; formed in any desired Inan- @5 pr fe'ahly by he usual punching die end oi the pawl The final complete forni of the plates is shown in Figs. l2 and i3, and 1G and 17. By bending the plates to this form the sides of lie punch projection and the side lli' die aperure will be inclined and'jifare". as sho n, 'this ii'ill provide die necessaiyl draft. rl`he bending of +die plates he performed in any well known manner, as by a sei of bending dies. By the use or this method a punch and die are produced which Will have the necessary draft Without requiring eX- pensive manual .filing-operations. lt Will be understood'that either the punch plaies or the die plates or both may be Hat as shown in Figs. 10, and l1, and lil and 15. ln such cases the draft is obtained in he usual Way, e., by filing. Moreover +he die may he of cylindrical form as shown and the vdraft niaY be obtained partially or Wholly hy filing or in any other suitable manner.

The operation of the machine will be as follows: blank is inserted in the carriage and this blank will be held in cylindrical form in the space le between the punches and dies. rThe blank is moved down eo its lowest position, and in such a position with respect to the cutting poiniJ opposite the pointer 59 Where it is desired to start the upper line of the stencil. The punch and die carriage is non7 elated eo position a selected set of punches and dies at the cutting point as noted hy the dial and pointer. The handle is nonv downufardly (io 'the left Fig. 2). During the iirst pari of the movement oz vhe handle ihepin i3 Will enter the flared aperture 4e' and aline the selected set of punches and dies with respect lo the cutting pcini'. During ihis lrsi; movenien the pawl will also move into engagement with the raichet 7S and more the blank carriage laterally` one space. The arrangement of elements oie the mechanism is such that Athe blank carriage will be fed one space and 'set of punches and dies is now positioned ai the cutting point and the handle 54 is again operated. During the operation of the liandleche blank carriage will he moved circumferentially to space the blank with respect to lee' the cutting point so as to space the next stencil character, and this next stencil. chai`- acter will be. cut as before. ln this Way the successive stencil characters-can be cut, the blank carriage being nioved step by step to space the stencil characters in a stencil liiic. ln order to move the blank to space the nent stencil line, the handle 98 is moved downwardly (to the left Fig. 2) so as to cause the paw] 93 to engage one oi the grooves Sit and more the carriage vertically on thc shaftone space. When the handle is released the pawl will be returned to original position out oi engagement with the hub Gti as shown in Figs. 3 and 7, the carriage being retained in adjusted position by means oi the ball latch 10G.

The arms GT and the' strips .72 of the car-` rier ari so positioned with, respect to the teeth on thc ratchet 7S that a strip 72 will never come to rest at the cutting point and oppositev a punch and die when the poi'tion Yof the blank to be' cut is positioned at the cutting point opposite the pointer 59 and the rani 41. These strips will therefore not interfere with the free operation of the punches. Furthermore the arnis 67 will never come, to rest at the cutting point, so that these. arms being thin will not yobstruct the view ot' the blank at the cutting point.

ln the operation of the machine, the, operator will stand over the machine opposite the cutting point, v. c., to the left Figs. 1, 2 and ly referring to Fig. 3, it will be noted that the upper edge of the punch carrier 12 terminates at the upper edge of the punches and below' the upper edge of the dic carrier 11. The punch carrier and thepunches thereon are also spaced a sullicient distance from the die carrier and the dies thereon, and the blank carrier positions the Fig. Il. This will give the operator a clear i view of thc blank` more especially at the cuttlng point. This view is permitted in view ot' the Jact that (he punches and dies are so arranged as to expose thc blank at the cutting point, and in view otl the fact that the i blank is arranged at an angle to the horizontal, vinstead of in horizontal planes. The skeleton construction of the. carriage cxposes substantially the entire blank, and the supporting strips come at such points that vthey never come, opposite the blank at the cutting point. Moreover in view of the fac't that the carriage is moved vertically to space the. stencil lines, the cut stencil line will be raised4 above thc punch and die car- .i-ier, so that it will be in plain view. It Will be noted that the blank is supported at itsl bottom or below the punches and dies, or generally speaking, inwardly of. punches and dies. As will be seen from an inspec' nisni, etc., is placed in such aposition as topci-init the operator to normally position his eye in such a position as to see the cut stencil line positively, the cut stencil line can be moved out of and above the carrier when eut so as to expose the lines successively to the full view ot the operator. Since the cnt line is 'visible as soon as cut, and as soon as the blank is spaced for the next line, the operator can readily position the second line with respect to the first line, etc. The niachine is therefore entirely visible -so that it is not necessary to feed the blank back out oi the machine to expose the part having the stencil cut therein to view each time that such a view is desired.

Referring now to Figs. 20 to 28 inclusive, lll() designates a pair of end trames which support the punch and die carriers 111.

This punch and die carrier is of substantially U -haped section as shown in Fig. 23 and is open at both ends so as to provide a vertical space Jfor receiving the blank. The carrier has lugs 112 pivoted to the end l'raines 110 by means ot' bolts 113, and has slotted lugs 11+ connected by bolts 115 to the end frames. The bolts- 115 engage the slots 11G in the lugs 114, whereby the carrier 111 ma)Y be tilted and set at any suitable angle with respect to the horizontal, the ca rrier being clamped in adjusted position by ineans of the bolts 115. A

The carrier 111 has mounted thereon a series of die plates 11T, and this carrier is apertured as shown at 11S to permit the punchiiigs to be discarded. The carrier is slotted longitlulinally as shown at 119 so as to provide a slot extending along substantially the entire length of the carrier to receirey the blank feeding andliolding means as hereinafter described. r1`he carrier is braced on each side of the slot llt) by horizontal fianges 12() and 121. A series of punch plungers 122 are mounted to slide in flanges 122% and 12sL in'the carrier, and each of these plungers is provided with a punch 125A adapted to cooperatev with a die plate 11T. Each plunger is provided Awith a spring 126 bearing at one endl against the flange 123 and at its other end against the collar 12T secured to the plunger. The

The carrier is ribbed as shown in Figs. 21 and so :is to obtain a rigid construction-- A bleni; carriage oi' substantially il sh pcd construction is adapted to move along the carrier 111, and is supported thereon by rolls 136 and 13T engaging tracks 138 sind 139 respectirelyon the carrier 111. rhis carrier supports the mechanism for actuating the punches and for holding and feeding; the blank. An operating plunger lor rem 110 is mounted to slide in the carrier and is provided with e hooked end 141 adapted to engage corresponding hooked ends on the punch plungers 123. pin 112 on the ram 1&0 is adapted to cooperate with inclined slots 143 of a plate 144 mounted on the web 121 of the punch and die carri@ so 21s to aline the carrier with respect 'to a selected set of punches and dies. This plete is provided with the usuel characters so este form a dial plate. An operating lever 145 is pivoted et 116 between e pair of lugs 117 on the carriage and has a handle 1118. This lever is provided With a cani rib 149 einbraced bycem rolls 150 on the reni 140. Depression of the handle 1118 will operate to more the reni inwardly and thereby cause e selected of punches and dies to cooperate with the blank. rEhe lever may be returned by :i spring' 151, or it muy he returned niannelly.

The blank 154i is supported in the recess in the punch and die carrier by ineens of e hlnnk carriage comprising e flared holder or 'trough 1:35 extending along the ce 'rier and supported :it its ends by here 156 monted to slide vertically in miden-'sys in 'the ends oi the carrier 111.

Referring' now to "55. :ind 287 189 end 190 designate u pair'oi arms or hand le- 1vers mounted on and movable with the oerriegc end hei/ino' lholes receiving the elicits 181 find 'The :irins are provided collars or hubs 192 and 193 shaped recesses in c position the I it will frictionally clamp hubs and frictionally retain thearins in position, but this cap maybe provided with a pin 195 having a roundedend adapted to engage the arm 190 so as to hold it in adjusted position.

'hen the arm 190 is in the-position shown in the drawings the pawls 184 will be held out of contact with the bars 156 while the pawls 183 are permitted to move into engagement .with these bars. lf the arm 189 be Anow depressed the pawl 183 willI engage the notches 185 in the bars 156 and move the blank carriage vertically.V By oscillating vthe arm-189 the blank carriage will be raised step by step so as to feed the blank vertically. The blank carriage may be held in adjusted position by means of suitable latching means as hereinbefore described. In order tolower the blank carriage the arm- 190 is moved downwardly until its upper edge snaps over the pin 195, which will operate to move. the pawls 1823 out of engagement and throw the pawls 184 into engagementv with the bars 156. Oscillation of the. arm 189 will now operate to move the blank carriage downwardly step by step. lt will be understood that a spring may be provided to hold the arm 189 in normal position, but the arms 189 and 190 may be held in position friet'ionally as hereinbefore described.

At the time when the blank carriage is to be moved vertically the feeding mechanism must be placedin such a position as to re'- lease the blank. This construction will now be described'. The arm 189 has projecting therefrom an arm 196 which connects by a link 197. with a bar 198 sliding verticallyin bearings 199 and 200 on the carriage 185. rlhe upper end 201 of this bar coperates with a flared hole 202 in the plate 167, and a laterally extendingr branch 203, connected to the arm 198 at 204, coperates with a like flaredhole 205 in the plate. lVhen the arm 189 is moved downwardly to raise the blank carriage the ends 201 and 203 in the bar 198 will during the first part of the movement of the. arm be raised to engage the flared holes 202 and 205 and move the plate 167 against the tension of its springs 170, so as to move the wheel 166 and the block 173 out ot' engagement with the blank, thereby freeing the blank and permitting itA to be fed vertically by the Vertical movement of the blank carriage. The pawls 183-and the arm 179 are preferably so positioned with respect to the arm 196 that the pawls 183 will be out of engagement with the notches 185 when the ends 201 and 203 are out of'en'gagement with the holes 202 and 205, whereby the plate 167 will be retracted before the pawls 183 engage the notches 185. When the carriage is to be fed downwardly the blank is usually not in the machine. In view of thel fact'A however that thefeeding takes place while the arm 179 moves downwardly, the

blank will be disengaged by the wheel 166 and the block 173 during the greater part of this downward movement.

It is sometimes desirable to throw the block 1723 out of action without throwing theA feeding wheel 166 out of action. This accomplished as follows: Referring to Figs'f'.

and 26, 206 designates an eccentric pin threaded into the end 201 of the bar 198 and having handle projections 207. Then the pin is in the position shown yin Figs. 25 and 26 it is held entirely out of engagement with the edge of the hole 202; when however-it is moved through 180o it will operate to enblock 173 from the wheel 158 and the? plate 1741. This blank is then so positioned with respect to the cutting point, which cutting point is on aline with the feeding rolls, where it is desired 4to start the upper line of the. stencil. The carriage 135 is now moved so as to position'it with respect t0 a rl`he, blank is inserted in its carl"` ge v by slightly separating the wheel and the selected set of punches and dies. The opy erating handle 148 is now moved downwardly. and during this downward movement the blank will first be fed transversely one space and thereafter the punch and die will eoperate to'cut the blank. The handle is now returned to original position and the carrier is moved to plisition another selected set of punches and dies at the cutting point. vlf the handle is now again operated the. blank will be spaced during thefirst part of the movemint of the handle and thereafter the puncl-i and die will coperate to cut the blank. The yertical spacing is obtained by the operation of the arm or handle 189 as described heretofore. Y

lt will be noted that theendof the plate 174 is beveled to form a comparatively sharp straight edge. This plate will therefore sink slightly into the blank. -It will be noted also that the sunken line will be on a line with the wheels-158 and 166, and if the feed is in the direction ot the arrow Fig."

25 the rolls will pull the blank bet; een thetwomembers 173 and 174 cl'ampmg the* bl ank.

extends for somevdistance alongI the blank, the tendency :is to -feedy the blank' in. a straight line as determined by thewdirection of the straight edge of the plate 174, I

By means of this construction a very accurate feed is obtained along a straight line.

yThe axes of the feed Wlieels'lie on a line which. is always positioned along a selected set of punches and dies Whenpositioned at' the cutting point. The blank is therefore always supported at tbe cnt-ting point.

ln this construction, as .in the construction 'shown in Figs. l tov 28 inclusive, the blank is supported at an angle to the horizontal, and the parts are so constructed and arranged as to expose the blank at the cutting point and on either side. lThe feed wheels being placed below the punches and dies W'll not obstruct the blank. The Work ot the machine is therefore visible. The blanllv carriage is, ribbed for strength, for it will be noted that this carriage takes all the strain during the punching operation. The carrier lll may be tilted at any suitable angle with respect to the horizontal to suit the operator.

lt is sometimes desirable to cut a. circular stencil, that is, a stencil having,l the stencil characters arranged circnlarlyv thereon' \vith respect to a common center. Means for cutting such stencils are shown in Figs. 29 to 34 inclusive and these means are shown as attachments for the machines shown in Figs. l to 25 inclusive.
